I'm going to be in San Francisco for quick escape from Portland- (2 day mid-week excursion). I have an appointment at 6:45 on Union and Fillmore and I'm trying to find a great (can be expensive) place for an early dinner that's within 5-15 minute walk. I've come across some stuff on the web- Merenda, Betelnut (this one sounds interesting but very hectic). There were a few others, but they start serving too late to make my appt. All suggestions greatly appreciated. Thanks!
